If we select students at random at an elementary school and ask them what their family size is, will this be a good measure of household size? Or will our average be biased? If so will it overestimate or underestimate the true value? a) Evaluate the sampling method. Which of the following statements are true about this sampling method? (Select all statements that are true.)1. A person is standing 4.15 km from one end of the river and 5.33 km from the other end of the river as shown below.The angle between both paths is 37^circ .
